vertical borders to be wider than the horizontal borders.
u
Select a resolution that allows for the maximum number of colors possible.
Refer to the documentation delivered with the workstation for more information on
configuring the video display.
2 Understanding StudioZ SDI Functionality
With StudioZ SDI, you have the capability for real-time audio/video capture and playback.
StudioZ SDI provides these basic capabilities:
u
Capture of video and audio to hard disk.
u
Playback of compressed and uncompressed video and audio from hard disk.
u
Hardware image compression and decompression to and from host memory.
u
JPEG compression/decompression.
u
Video input/output.
Uncompressed Capture and Playback
StudioZ SDI can capture and play back uncompressed video at full size and full rate. In this
mode, the compression setting or Video Quality level is ignored. During video capture, the
compression circuitry is bypassed and the uncompressed video is transferred to system
memory, and then to the disk drive. During playback the process is reversed, again bypassing
the decompression circuitry.
7
You can vary the size, brightness, contrast, hue, and saturation of the video as it is captured or
played back in either compressed or uncompressed mode. You also can build video sequences
from bitmaps generated by other applications.
JPEG Compression/Decompression
StudioZ SDI can capture and play back full-rate, full-frame video while performing hardwareaccelerated motion JPEG compression and decompression. As video frames are digitized,
they may be JPEG compressed, written to system memory, and then written to hard disk. This
compression reduces the disk data rate required for full-rate, full-frame capture. The actual
disk data rate is a function of the Video Quality value set during StudioZ SDI driver
configuration, the image content of the video captured, and the amount of hard disk space that
is used.
Motion JPEG encoding is an intraframe compression scheme. Each field is compressed
individually, allowing frame boundary editing at any point in the video. The reconstructed
JPEG image is not a bit-for-bit copy of the original image. You can adjust the image quality
by changing the Video Quality value during StudioZ SDI driver configuration.
8
You can compress images (raster data blocks) in system memory and then store them in
system memory. You can also decompress compressed images, with system memory serving
as both the source and destination. With the exception of 720 x 486, images must be
composed of an integer multiple of 16 x 16 pixel blocks.
StudioZ SDI provides direct memory access (DMA) capability to allow compression and
decompression to occur with minimal host processor intervention.
Video I/O
StudioZ SDI accepts SDI input in either 525 line/59.94 Hz (NTSC) or 625 line/50 Hz (PAL)
format. The 10-bit-per-component input is processed by input lookup tables for 10-bit-percomponent to 8-bit-per-component transformation, and for brightness, contrast, hue, and
saturation adjustment.
The StudioZ video encoder takes digital YUV 4:2:2 data and produces SDI, S-video, and
composite outputs in either 525/59.94 Hz or 625/50 Hz formats. Lookup tables convert 8-bitper-component output data to 10-bit-per-component output data and can provide brightness,
contrast, hue, and saturation adjustment.

Real-Time Video Capture
The video data are received from the external video source (SDI Input) as fields of 243
(for 525/59.94 systems) or 288 (for 625/50 systems) visible lines. Input sequences vary
and can be as short as one frame, or as long as disk space and the application software
allows.
You can monitor the video capture process on the Composite, S-video, or SDI outputs.
The video output is line-locked to the input with a fixed delay between input and output.
In capture mode, the video input displays continually regardless of whether video capture
is enabled or disabled.
When video capture is triggered, capture begins with the next odd field of incoming
video. If the video sequence cannot be stored in memory quickly enough to maintain full
frame rates, you may encounter dropped frames. If this happens, StudioZ notifies you,
and duplicates input frames as necessary to produce a seamless video sequence.
Real-Time Video Playback
9
Frames are played back as two individual fields. Output sequences can be as short as one
frame, or as long as disk space and application software allow.
If the video sequence cannot be played back fast enough to maintain full frame rates, you may
encounter dropped frames. See “Real-Time Video Capture” in this chapter for information on
dropped frames.
See Chapter 3 for more information on capture and playback capabilities.

3 Capturing and Playing Back V i deo
This chapter provides tips for obtaining optimum video quality when capturing and playing
back video using the StudioZ SDI card.
Video Capture
For optimal video capture results, you must manage two parts of the capture process — the
input video signal and the video data rate.
To manage the video digitizing process, follow these guidelines:
u
Set the video format correctly. North America and Japan use the NTSC standard of
525 lines and 59.94 Hz. Almost all of Western Europe (excluding France) uses the PAL
standard of 625 lines and 50 Hz. If you are unsure of your video standard, consult your
video equipment engineer. You must capture and play back video in one video format.
u
Ensure that the video source supplies SDI. StudioZ SDI accepts only SDI input. SDI
provides video quality superior to S-video or Composite/Component analog formats. If
the video source does not supply SDI directly, third-party converter boxes are available to
convert from all other popular formats into SDI.
11
To achieve optimum disk data rates, you should defragment the disk drive periodically. There
are two ways to defragment a disk drive: use a disk utility program to reorder the files on the
disk and remove the gaps between the files, or delete all of the files on the disk. If you delete
the existing files and write new ones to the disk, there will be no disk fragmentation (gaps) as
long as you do not delete any files during the write process.
CAUTION Never use the system’s primary hard disk drive (usually drive C:\) to capture digital video data.
Video Playback
For the best video playback performance, follow these guidelines:
u
Play video in the format in which it was created. You cannot play back NTSC video
as PAL video or vice-versa. You can play back only video that was originally
compressed with the StudioZ SDI card or compatible codecs.
u
Use the highest-quality output signal. The SDI signal provided by the SDI OUT
connector is the highest quality output available on StudioZ SDI. S-video OUT and
Composite OUT both are active simultaneously with SDI OUT. They may be viewed on
analog monitors or recorded. S-video output is of higher quality than composite output.
12
4 Using the SDI Video Control
The SDI Video Control is a utility delivered with your StudioZ SDI card. This utility lets you
adjust the color levels, contrast, and brightness of the video data as it is captured or played
back using the StudioZ SDI card.
NOTE Adjustments made to video that you capture to an AVI are retained by the video data stored in
the file. Changes you make to video being played back affect only the video output and do
not change the data in the AVI. If you want to save the adjustments you make with SDI Video
Control during playback, you must record the video output to video tape.
Displaying the SDI Video Control
To display the SDI Video Control:
From the Windows NT Programs menu, go to StudioZBurst/SDICtrl. The SDI Video Control
dialog displays:
13
14
Adjusting Brightness and Color
You can use the SDI Video Control to change the luminance (brightness) and chrominance
(color) of a video sequence.
Changing the Luminance of a Video Sequence
The sliders under Luminance in the SDI Video Control allow you to adjust the brightness of
the video data. The Gain slider controls the overall brightness level of objects in the video.
The Setup slider controls the black levels, or overall brightness, of the entire video picture.
For example, your video shows planets orbiting a sun in deep space. Moving the Gain slider
adjusts how bright the sun, nearby stars, and the planets appear against the black background.
Moving the Setup slider adjusts the overall picture brightness — in other words, whether the
deep space background appears to be black or a washed-out gray.
To adjust brightness in a video sequence:
1. Under Mode in the SDI Video Control, click Capture if you want to adjust the input
video, or Playback if you want to adjust the output video.
2. Under Range Limits, select Compress ranges to CCIR 601 if you want to limit the values
for the luminance. If you select this option, the luminance values are limited from 32
through 438 only.
3. Under Luminance, drag the Gain slider to adjust the brightness of the objects in the video.
For example, use this slider to change very bright objects (such as stars in a star field) to
be barely visible against a dark background.
– OR –
Key in a value between -12dB and +12dB.
4. Under Luminance, drag the Setup slider to adjust the brightness of the entire picture in the
video. Using this slider is much like turning a knob to adjust the brightness of your
monitor screen.
– OR –
Key in a value between -63.6 and 63.5.
Next you will adjust the colors in the video sequence, so do not close the SDI Video
Control.
Changing the Chrominance of a Video Sequence
The sliders under Chrominance in the SDI Video Control manipulate the colors of the video.
The Gain slider controls the color shade of objects in the video. The Phase slider controls the
primary color of objects in the video. For example, your video of planets orbiting the sun
shows three red planets. Move the Gain slider to adjust how red the planets are — light red,
dark red, rosy red, blood red, and so on. Move the Phase slider to change the color shades of
the planets from red to orange, yellow, green, blue, or purple — all of the colors contained in
the visible spectrum.
To adjust the colors in a video sequence:
1. Under Chrominance, drag the Gain slider to adjust the color shade of the objects in the
video. For example, you can change a dark green object to olive green, neon green, forest
green, or pale green.
– OR –
Key in a value between -12dB and +12dB.
2. Under Chrominance, drag the Phase slider to adjust the primary color of objects in the
video. For example, change a blue object to purple, red, yellow, pink, or orange.
– OR –
Key in a value between -180 degrees and +180 degrees.
15
Next you will set some default values, so do not close the SDI Video Control.
Setting Default Values
You can set default values for the luminance and chrominance. Once you set defaults, you can
quickly return the luminance and chrominance to their original values after you modify them.
To set default values for luminance and chrominance:
1. Under Luminance, drag the sliders for Gain and Setup to the brightness levels you
require.
2. Under Chrominance, drag the sliders for Gain and Phase to the color intensity you
require.
3. Click the Change Defaults button. The default values are now set. If you make changes
to the color and brightness of the video and later want to return to the default values you
just set, click the Load Defaults button.
Once you have finished adjusting the parameters on the SDI Video Control, click OK. Your
changes are applied and the SDI Video Control is dismissed.

is the blanking level of this scale.
NTSC (no pedestal) Specifies the NTSC format in terms of lines and frames per second.
The difference between NTSC (no pedestal) and NTSC is that black is
at the blanking level (0 IRE). NTSC (no blanking) is used mainly in
Japan.
PAL Specifies that the Phase Alternate Line (PAL) format of 625 lines (576
visible), 25 frames/second is the video display standard. PAL is
widely used in Europe.
ock Forma
Specifies that the external monitor format matches the video format
specified in the StudioZBurst Driver Configuration dialog box, and is
not affected by video format changes in any application or the format
of the AVI being played back.
When Lock Format is selected, you must play back video that was
captured in the same format as the one specified here (either NTSC or
PAL). If you try to play back a video sequence that was captured in a
format other than the one specified, the video sequence could play
back at the wrong speed and the audio will be out of sync.
In most cases, you must close any application that relies on the
StudioZBurst driver before changing the driver configurations.
However, StudioZ Central Plus lets you change the video format from
within the application, provided Lock Format is turned off. This lets
you play both NTSC- and PAL-formatted clips correctly without
having to close the application and modify the StudioZBurst driver
configurations. This is useful if you regularly work with both NTSC
and PAL formats.
Parameter Description
Playback Display Specifies the video output display device. Select External Monitor or
Computer Screen.
External Monitor Specifies that the output display device is the external video monitor
connected to the StudioZ SDI board. This setting provides the best
video quality and performance, and is the default.
Computer Screen Specifies that the video output display devices is the monitor
connected to your workstation. You should use the computer screen
only as a diagnostic tool.
Video Compression Specifies the type of compression applied to the captured frame.
JPEG Compressed Provides the optimum data rate using compressed capture.
21
Uncompressed
(YUV 4:2:2)
Capture Frame
Dimensions
Specifies that luminance and chrominance values are obtained during
a capture, and does not apply any compression to the captured data.
Specifies the size at which frames are captured. Video data is
normally captured at full frame sizes, which are 720 x 486 for NTSC
(525 line, 59.94 Hz) and 720 x 576 for PAL (625 line, 50 Hz). You
can resample video data on capture to lower resolutions or square
pixel sizes to meet your requirements.
For compressed capture, the width and height must be a multiple of 16
(with the exception of 720 x 486).
For uncompressed capture, width and height must be a multiple of 2.
Width Specifies the horizontal size of captured frames.
Height Specifies the vertical size of captured frames.
Genlock Synchronizes the video output signal with the reference signal input
(also known as house sync).
The genlock parameters are disabled if you do not have an MSMT383
(or later) board.
Phase Adjust Allows you to fine-tune the synchronization of the subcarrier output
timing. Use the scroll arrows to change the phase adjust value.
Reference Enable Allows the use of an internal or an external genlock source.
Reference Enable is on by default if you loaded the Intergraph
StudioZBurst driver. If you do not have a house sync, Reference
Enable will cause sync, color, and scrolling problems in your external
monitor. To prevent these problems, turn off Reference Enable if you
do not have a house sync.

Parameter Description
Continue Accepts the settings and returns you to the Drivers dialog.
Close Dismisses the dialog without accepting any changes to the driver
configuration.
6 Troubleshooting StudioZ Operation
This chapter provides guidelines for troubleshooting problems that may occur with StudioZ
SDI during setup or during normal use. Problems with StudioZ may be hardware-related
failures such as bad or disconnected cables. Other problems may be due to incorrect
configuration of StudioZ SDI.
Before referring to the guidelines on the following pages, ensure the following:
u
The StudioZ SDI card is installed correctly.
u
All external customer-supplied capture and playback equipment, including customersupplied cabling and converters, is in good working order. You can verify the working
condition of this equipment by connecting the input video source (VTR or camera)
directly to the video output device(s) (display monitor(s) or VTR). This verifies end-toend operation of all non-StudioZ SDI equipment and interconnection cabling.
Certain frames in the video sequence are not displayed during capture and
playback.
StudioZ SDI may drop frames if excessive activity occurs during video or audio capture and
playback. Real-time broadcast quality video or audio capture and playback place a great
demand on system resources. To obtain the best performance, follow these suggestions during
capture and playback:
23
u
Disable access to shared files from the network.
u
Disable programs (such as virus scanners or batch files) that may run automatically.
u
Do not load these InterSite programs: ECC Memory Monitor (ECCMEM), SMART Disk
Driver (SMARTDRV), or Hardware Monitor (HWMON).
u
Do not read or send email, or run a program that sends or receives email.
u
Do not run screen savers, a World Wide Web browser, or a Usenet news reader.
u
Do not transfer files to or from system disks, or to and from systems via the network.
You may find it helpful to isolate your workstation from the network and verify that no other
programs are running before you capture or play back video.
Blank video image or poor quality video image is captured during a video
capture sequence, and the input video source is an SDI device.
u
Verify that the video input source is connected to the SDI IN port on the StudioZ board
edge panel.
u
Verify that the external video source is powered on and operational.
24
Poor quality video image, bad colors, or blank screen is displayed on the SDI
output during a video capture sequence or a normal playback sequence.
u
Verify that the external video display monitor is connected to the SDI OUT port on the
StudioZ board edge panel.
u
Verify that the external video source is powered on and operational.
u
Verify that the external video display monitor is powered on and operational.
Poor quality video image, bad colors, or blank screen is displayed on the
S-video output during a video capture sequence or a normal playback
sequence.
u
Verify that the external video display monitor is connected to the S-video Output port on
the StudioZ board edge panel.
u
Verify that the external video source is powered on and operational.
u
Verify that the external video display monitor is powered on and operational.
Poor quality video image, bad colors, or blank screen is displayed on the
Composite Video output during a video capture sequence or a normal playback
sequence.
u
Verify that the external video display monitor is connected to the Composite output port
on the StudioZ board edge panel, and that it provides the necessary 75-ohm termination
load for the composite video output.
u
Verify that the external video source is powered on and operational.
u
Verify that the external video display monitor is powered on and operational.
When capturing a video sequence, background noise is present in the audio
portion of the captured sequence.
Disable the Mic Input source. Other input sources may be disabled as well.
